The rest of the country uses diesel for it's frieght.They also use diesel for their passenger service too, so either way LI is abnormal. If the Cross Harbor Freight Tunnel ever gets built it will most likely use electric traction, so then LI's third rail connection to the outside world world will require electric locos and the other two will be wired. Every siding would need to be elctrified. Not neccesarily. The New York Central had trimode switchers which were capable of operating on third rail, battery, or diesel power, it wouldn't be overly difficult to make a similar unit today. Give it a pantograph and transformer, third rail shoes, and a 1500hp 8cylinder engine, and size it such that it'd be capable of maybe 3000 to 4000hp on the wire, 2500-3000hp on third rail, and 1500hp in diesel. Thus you'd have a unit capable of pulling a long freight through the tunnel from NJ or across the Hell Gate from the Bronx, breaking it up at a yard in Brooklyn, hauling the pieces on third rail to their destinations on LI, and finally switching them to those places on diesel power. Or you could just have diesel switchers MU'd with the AC/DC locos doing the heavy lifting; the switcher would couple out of the motive power lashup to switch industries along the route. |
